OBJECTIVE: Thyroid dysfunction, a common complication of pregnancy, is associated with adverse obstetric and neonatal consequences. This study aimed to determine the effect of TSH levels on early pregnancy outcome in a prospective population-based cohort study. DESIGN AND METHODS: The serum TSH, free thyroxine, free triiodothyronine, thyroid peroxidase antibody levels and urinary iodine concentration of 418 pregnant women in their first trimester of pregnancy were measured. According to the American Thyroid Association (ATA) and the local reference ranges for TSH, women were divided into two groups of 0.1-2.5, >2.5 mIU/L and 0.2-4.6, >4.6 mIU/L. The risk of spontaneous abortion (SA) was calculated for each group. RESULTS: Spontaneous abortion was detected in 7.2% (n = 30) of total 418 pregnancies. Women with TSH levels > 2.5 mIU/L had an increased risk of SA, compared to women with TSH levels of 0.1-2.5 mIU/L (relative risk [RR] 3.719, 95% confidence interval [CI]:1.713-8.074). The risk of SA was increased in women with TSH levels > 4.6 mIU/L (RR 5.939, 95% CI: 1.711-20.620). The rate of SA was increased by 78% for every unit increase in standard deviation of TSH concentration (RR 1.35, 95% CI: 1.09-1.70). The rate of miscarriages in the treated group by levothyroxine was 9.8% (n = 6) compared to 28.6% (n = 8) in the untreated group (P = 0.024). CONCLUSIONS: Our finding suggests that the upper limit for the TSH normal range should be redefined to <2.5 mIU/L during the first trimester of gestation. The local upper limit was 4.6 mIU/L, consistent with 4.0 mIU/L cut-off value recommended by the ATA.

The physiological changes during pregnancy modulate the endocrine system. Therefore, both the American and the European thyroid associations recommend the use of local trimester-specific reference intervals. The purpose of this study was to establish the first trimester reference intervals for thyroid function tests in the central area of Iran. We examined 436 pregnant women in their first trimester of pregnancy, and 444 non-pregnant women in a cross sectional study. Serum levels of thyroid stimulating hormone (TSH), free thyroxin (FT4), free triiodothyronine (FT3), thyroid peroxidase antibody, urinary iodine concentration (UIC), and thyroid volume were measured for all subjects. The first trimester-specific reference intervals (2.5th-97.5th percentile) were determined for 185 pregnant women and 256 non-pregnant women with negative TPOAb, adequate iodine level (UIC≥150 µg/l in pregnant and UIC≥100 µg/l in non-pregnant women), and normal thyroid examination. We calculated multiples of the median (MoM) for TFTs to normalize the obtained data. The first trimester-specific reference intervals of serum TSH, FT4, and FT3 for pregnant women were 0.20-4.60 mIU/l, 9.0-18.02 pmol/l, and 3.40-5.64 pmol/l, respectively, while the corresponding figures for non-pregnant women were 0.59-5.60 mIU/l, 9.52-19.30 pmol/l, and 3.70-5.55 pmol/l, respectively. The first and 99th percentile MoM of TSH in pregnant women in their first-trimester was 0.06-4.62. The local normal reference ranges for the first trimester of pregnancy in central region of Iran were different from the ranges suggested by the ATA.

BACKGROUND: The aim of this study was to evaluate the self-reported perceived quality of life (QoL) in female to male (FTM) and male to female (MTF) transgenders and compare it with a general population sample, and to find possible determinants that likely contribute to their QoL. METHODS: Participants were 71 trandgenders participating in the communities of Isfahan and Fars provinces, Iran, including 30 MTF and 41 FTM, and 142 gender- and age-matched controls. Persian version of the Short Form 36-Item Questionnaire was used to evaluate self-reported QoL, which measures QoL across eight domains. RESULTS: Compared to control group, the QoL of transgenders in the most dimensions of the SF-36 questionnaire was lower. MTF had a lower QoL than FTM for the subscale physical functioning (p = 0.044). There was a significant relationship between education and subscales of emotional well-being (p = 0.048) and social function (p = 0.008); economic status and physical function subscale (p = 0.003); employment status and physical function (p = 0.012) and social function subscales (p = 0.003). Compared to male controls, MTF transgenders had lower physical functioning (P < 0.001), role limitation due to physical health (P = 0.015), vitality (P = 0.023), social functioning (P < 0.001) and pain score (P = 0.044) and no significant differences between female controls and FTM transgenders were seen. CONCLUSION: Transgenders have lower physical and mental QoL, FTM transgender has better QoL than MTF transgender. Employment, education, province of residence and economic status as well as therapeutic intervention is associated with transgender's QoL.

BACKGROUND: This paper presents the protocol and primary findings of pregnancy cohort population-based study in Isfahan, Iran. MATERIALS AND METHODS: In this cohort, 418 pregnant and 438 nonpregnant women were enrolled. In the first phase, serum concentrations of thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), thyroid peroxidase antibody, and urinary iodine concentration (UIC) were measured. Furthermore, the thyroid ultrasound was also performed. According to the results of thyroid function tests in the first phase, local reference range for TSH, FT4, and FT3 in pregnant and nonpregnant women are determined. The 2.5th and 97.5th percentiles are determined as limits of the reference ranges. In the second phase, all pregnant women underwent prenatal care visits in each trimester and they followed for 7 days after delivery and the pregnancy outcomes data are reported. RESULTS: The mean ± standard deviation for TSH, FT4, FT3, and UIC in the first trimester of gestation was 1.84 ± 1.32 mIU/L, 1.01 ± 0.15 ng/dL, 4.50 ± 0.64 pmol/L, and 172.0 ± 90.29 µg/L, respectively. In nonpregnant women, these values for TSH, FT4, FT3, and UIC were 2.58 ± 1.77 mIU/L, 1.10 ± 0.21 ng/dL, 4.49 ± 0.57 pmol/L, and 190.0 ± 109.6 µg/L, respectively. CONCLUSION: The results of the present study could contribute to establish a local thyroid function tests reference ranges in the first trimester of pregnancy. It could possibly be effective on making a local reference value to prevent of thyroid disease misdiagnosis during pregnancy and adverse pregnancy outcomes.
ABSTRACT
BACKGROUND: In this study, we evaluate the association between triglyceride to high-density lipoprotein cholesterol (TG/HDL) ratio and total cholesterol (TC) to HDL (TC/HDL) ratio and the risks of type 2 diabetes (T2D) in an Iranian high-risk population. METHODS: We analysed 7-year follow-up data (n = 1771) in non-diabetic first-degree relatives of consecutive patients with T2D 30-70 years old. The primary outcome was the diagnosis of T2D based on repeated oral glucose tolerance tests. We used Cox proportional hazard models to estimate hazard ratio for incident T2D across tertiles of TG/HDL and TC/HDL ratios and plotted a receiver operating characteristic (ROC) curve to assess discrimination. RESULTS: The highest tertile of TG/HDL and TC/HDL ratios compared with the lowest tertile was not associated with T2D in age- and gender-adjusted models (HR 0.99, 95% CI: 0.88, 1.11 for TG/HDL ratio and 1.10, 95% CI: 0.97, 1.23 for TC/HDL ratio). Further adjustment for waist circumference or body mass index, fasting plasma glucose, and low-density lipoprotein cholesterol did not appreciably alter the hazard ratio compared with the age- and gender-adjusted model. The area under the ROC curve for TG/HDL ratio was 57.7% (95% CI: 54.0, 61.5) and for TC/HDL ratio was 55.1% (95% CI: 51.2, 59.0). CONCLUSIONS: TG/HDL and TC/HDL ratios were not robust predictors of T2D in high-risk individuals in Iran. Copyright © 2015 John Wiley & Sons, Ltd.

BACKGROUND/AIM: It is not clear whether levels of continuous metabolic syndrome (cMetS) are associated with type 2 diabetes (T2D). The aim of this study was to determine the ability of the cMetS score to predict progression to T2D in non-diabetic first-degree relatives (FDRs) of patients with T2D in Isfahan, Iran. METHODS: A total of 1,869 non-diabetic FDRs 30-70 years old in 2003-2005 were followed through 2014 for the occurrence of T2D. At baseline and through follow-ups, participants underwent a standard 75 g 2-h oral glucose tolerance test. MetS was defined by the National Cholesterol Education Program-Adult Treatment Panel III. The cMetS score was calculated using age- and gender-standardized Z-score for MetS components. Receiver operating characteristic (ROC) curve was used to assess the association between cMetS and components of MetS with T2D. RESULTS: During 13,571 person-years of follow-up, 72 men and 210 women developed diabetes. Those in the top quartile of cMetS were 8.0 times more likely to develop diabetes than those in the bottom quartile (OR 7.96; 95% CI 4.88-12.99). On ROC curve analysis, a higher area under the ROC were found for FPG (74.3%; 95% CI 70.8-77.8), than for cMetS (69.4%; 95% CI 66.0-72.8). CONCLUSIONS: The cMetS score is a robust predictor of T2D and may be more effective and efficient than the current binary definition of MetS in predicting progression to T2D in our study population.

This paper reports the results of a comparative investigation of attitudes to suicide and suicidal persons in 5,572 university students from 12 countries. Participants filled out two scales measuring attitudes towards suicide and suicidal persons, a measure of psychological distress together with the questions about suicidal behavior. Results showed that the highest suicide acceptance scores were observed in Austrian, UK, Japanese and Saudi Arabian samples and the lowest scores were noted in Tunisian, Turkish, Iranian and Palestinian samples. While the highest social acceptance scores for a suicidal friend were noted in Turkish, US, Italian and Tunisian samples, the lowest scores were seen in Japanese, Saudi Arabian, Palestinian and Jordanian samples. Compared to participants with a suicidal past, those who were never suicidal displayed more internal barriers against suicidal behavior. Men were more accepting of suicide than women but women were more willing to help an imagined suicidal peer. Participants with accepting attitudes towards suicide but rejecting attitudes towards suicidal persons reported more suicidal behavior and psychological distress, and were more often from high suicide rate countries and samples than their counterparts. They are considered to be caught in a fatal trap in which most predominant feelings of suicidality such as hopelessness or helplessness are likely to occur. We conclude that in some societies such as Japan and Saudi Arabia it might be difficult for suicidal individuals to activate and make use of social support systems.

BACKGROUND: Insulin receptor substrate (IRS) Type 1 is a main substrate for the insulin receptor, controls insulin signaling in skeletal muscle, adipose tissue, and the vascular, so it is an important candidate gene for insulin resistance (IR). We aimed to compare the effects of the Dietary Approaches to Stop Hypertension (DASH) and Usual Dietary Advices (UDA) on IRS1 gene expression in women at risk for cardiovascular disease. MATERIALS AND METHODS: A randomized controlled clinical trial was performed in 44 women at risk for cardiovascular disease. Participants were randomly assigned to a UDA diet or the DASH diet. The DASH diet was rich in fruits, vegetables, whole grains, and low-fat dairy products and low in saturated fat, total fat, cholesterol, refined grains, and sweets, with a total of 2400 mg/day sodium. The UDA diet was a regular diet with healthy dietary advice. Gene expression was assessed by the real-time polymerase chain reaction at the first of study and after 12 weeks. Independent sample t-test and paired-samples t-test were used to compare means of all variables within and between two groups respectively. RESULTS: IRS1 gene expression was increased in DASH group compared with UDA diet (P = 0.00). Weight and waist circumference decreased in DASH group significantly compared to the UDA group (P < 0.05) but the results between the two groups showed no significant difference. CONCLUSION: DASH diet increased IRS1 gene expression and probably has beneficial effects on IR risks.
ABSTRACT
BACKGROUND: There is accumulating evidence for a possible protective role of vitamin D in the development and disease course of multiple sclerosis. Whether vitamin D is also effective in treating patients with optic neuritis (ON) is not known. The aim of this study was to evaluate the effect of oral vitamin D on the thickness of retinal nerve fiber layer (RNFL) in vitamin D deficient patients with ON by optical coherence tomography. MATERIALS AND METHODS: A Phase II placebo-controlled randomized clinical trial conducted between July 2011 and November 2012 included 52 patients with confirmed unilateral ON aged 15-38 years and low serum 25-hydroxyvitamin D levels. The main outcome measures were changes in thickness of RNFL and macula 6 months after treatment. Patients were randomly allocated to receive 6 months of treatment with adding either 50,000 IU/week vitamin D or placebo. RESULTS: In the 27 patients treated with vitamin D, the mean (standard deviation [SD]) thickness of RNFL decreased from 111.3 (18.9) µm at baseline to 91.4 (13.3) at the end of study period (P < 0.001). Correspondingly, in the 25 patients treated with placebo, the mean (SD) thickness of RNFL decreased from 113.7 (21.5) µm at baseline to 96.1 (12.3) at the end of study period (P < 0.01). In both groups, the mean thickness of the macula did not changed (P > 0.05). Average thickness of RNFL at the end of trial did not differ between groups. CONCLUSION: Adding vitamin D to routine disease therapy had no significant effect on the thickness of RNFL or macula in patients with ON. This trial is registered on www.clinicaltrials.gov (ID NCT01465893).
ABSTRACT
INTRODUCTION: Sexuality is an important aspect of human life and sexual problems are common, but there is limited evidence for cost-effective treatments of women's sexual dysfunctions. AIMS: The aim of this study was to assess whether group therapy such as Sexual Health Model (SHM) can be as effective as individual therapy like Permission, Limited Information, Specific Suggestions, and Intensive Therapy (PLISSIT) model in women with sexual problems. METHODS: A randomized controlled trial was conducted between May 2012 and September 2013 in five Tehran, Iran health clinics. Eighty-four consecutive married women aged 20-52 years, with sexual problems who were admitted for the first time, were recruited and randomized into two groups. The intervention included two therapeutic models: the SHM, which consisted of two sessions of 3 hours of group education, and the PLISSIT model, which required a total of 6 hours of one-on-one consultation at an interval of 1-2 weeks. MAIN OUTCOME MEASURES: Sexual function and sexual distress were assessed, respectively, with the Brief Index of Sexual Function for Women and Female Sexual Distress Scale Revised questionnaires. RESULTS: Seven months after intervention, the mean (SD) of the sexual distress score decreased and sexual composite score increased significantly in both groups (P < 0.001). The overall analysis of repeated measure manova revealed borderline significance differences for combined outcomes between two groups (P = 0.051). CONCLUSIONS: Due to the considerable human resource, time, and cost spent conducting the PLISSIT, it seems that group education based on SHM could be more cost-efficient and nearly as effective. This conclusion may be more applicable in communities where the treatment of sexual problems is in the beginning stages and where people have not received any sexual education or knowledge during their lifetime.

The present systematic review and metaanalysis of published observational studies was conducted to assess the health effects of exposure to air pollution on diabetes risk. Online databases were searched through January 2013, and the reference lists of pertinent articles reporting observational studies in humans were examined. Pooled relative risks and 95 % confidence intervals were calculated with a random-effects model. Exposure to air pollution was associated with slight increase in risk of diabetes and susceptibility of people with diabetes to air pollution. These results were consistent between time-series, case-crossover and cohort studies and between studies conducted in North America and Europe. The association between exposure to air pollution and diabetes was stronger for gaseous pollutants than for particulate matter. Our metaanalysis suggests that exposure to air pollution may be a risk factor for diabetes and increase susceptibility of people with diabetes to air pollution.

The aim of this study was to examine the impact of a brief psychoeducation group intervention on fear and anxiety in patients undergoing the coronary artery bypass grafting (CABG). Sixty consecutive patients undergoing CABG for the first time were recruited for a clinical trial and randomized into two groups. The control group received routine care. The study group received a brief psychoeducation group intervention combined with routine care. The psychoeducation session consisted of a discussion of fear and anxiety in a psychotherapeutic atmosphere and relaxation techniques. Fear was scored with the Bypass Grafting Fear Scale (BGFS) and anxiety was scored with the Spielberger State Inventory (STAI) Questionnaire. The BGFS and the STAI were given to the patients the day after hospital admission and a day before the operation to measure fear and anxiety. Fear scores decreased in the psychoeducation group. Of the 29 patients treated with psychoeducation, the mean (SD) fear score decreased from 4.6 (1.7) at baseline to 2.8 (1.2) before the operation (p < .001). In the 31 patients who received routine care, there was a nonsignificant trend from 3.7 (1.9) to 4.1 (2.1) (p > .05). The mean difference in fear score before the operation was significantly lower in the psychoeducation group than the routine care group (mean difference -1.3; 95% CI, -2.1, -.2; p < .05). There were no differences in anxiety scores before the operation between the psychoeducation and routine care groups. In patients undergoing CABG, adding psychoeducation to routine care had a significant positive effect on fear but not on anxiety scores. A larger study of psychoeducation in these patients is warranted to assess the efficacy of this intervention in greater detail.

BACKGROUND: Non-contrast computed tomography (NCCT) is the diagnostic choice for renal stone disease. Knowing the composition of a stone before passage can help to choose a better management. We sought to determine whether the Hounsfield unit (HU) measured by NCCT can predict the composition. MATERIALS AND METHODS: 180 urinary stones from patients seen at Shariati, Kashani and Alzahra CT centers, were submitted to stone analysis, 2012. All scans had been interpreted for HU. Primitive statistical findings showed an effect of size on the HU. To avoid confounding bias, Hounsfield Density (HD: HU/largest transverse diameter) was calculated. Statistical comparisons were performed between composition with HU and HD. RESULTS: Calcium stones had specific ranges for HD and HU. No non-calcium stone had HU more than 448 and HD greater than 50 HU/mm. CONCLUSION: NCCT can differentiate just Calcium from non-calcium stones.
ABSTRACT
BACKGROUND: Health science students are at an increased risk of hepatitis A virus (HAV) infection even under accidental infection. The aims of this study were to assess the seroprevalence of HAV in 1(st) year medical students and to determine the risk factors of HAV vaccination program among this population. MATERIALS AND METHODS: A cross-sectional study was conducted in autumn 2010. A total of 1028 newly admitted medical students in Isfahan, Kermanshah and Hamedan were included in the study. Participant data were obtained through predesigned data collection sheets. A serum sample was obtained for serologic testing for the presence of IgG anti-HAV using a commercially available enzyme-linked immunosorbent assay kit. Descriptive statistics, Chi-square and logistic regression tests were performed for statistical analysis and P < 0.05 was considered as significant. RESULTS: The prevalence of HAV was detected in Isfahan, Hamedan, and Kermanshah newly admitted students 67.5%, 79.2%, and 50.6% respectively. There were significant relations between anti-HAV (IgG) positivity in drinking water and medical students provinces (P < 0.001, RR = 0.58 and 0.65 respectively). The household size did not significantly influence the anti-HAV (IgG) positivity in studied subjects (P = 0.09, RR = 1.26). CONCLUSION: Our results indicate that more than one-third of the medical students in all three faculties were seronegative for IgG anti-HAV and hence at an increased risk of developing HAV infection as a result of occupational exposure. Therefore, we suggest students in a health care set up should undergo vaccination against HAV after prevaccination immunity screening.
ABSTRACT
BACKGROUND: Although several studies have investigated the association between maternal exposure to air pollution and preterm birth, the results are inconsistent. The aim of this study was to further investigate the relation between maternal exposure to ambient air pollution during pregnancy and the risk of preterm birth and low birth weight (LBW) in an Iranian pregnant population. MATERIALS AND METHODS: In this study, we identified 4758 consecutive singleton birth records from one large referral hospital (2010-2012) in Isfahan, Iran. We identified cases of preterm birth and LBW, which were combined with meteorological and air pollution monitoring data. We estimated the effect of air pollution exposure during the entire pregnancy, each trimester, and last month, and preterm birth (gestational age <37 weeks) and LBW (<2500 g) by Pollutant Standard Index (PSI) using logistic regression adjusted for gestational age, neonate gender, birth order, and mother's age. RESULTS: The PSI for entire pregnancy was significantly associated with preterm birth [Odds Ratio (95% CI) = 1.26 (1.20, 1.33)]. There was no association between maternal exposure to ambient air pollution and each trimester and the last month of pregnancy, and preterm birth or LBW. CONCLUSION: Maternal exposure to ambient air pollution during the entire pregnancy was associated with preterm birth in Isfahani women.
ABSTRACT
OBJECTIVE: To compare the effect of betamethasone and dexamethasone on maternal white blood cell (WBC) and differential count, erythrocyte sedimentation rate (ESR), Apgar score, maternal and fetal plasma glucose and length of admission to delivery, gestational age at delivery in women at risk of preterm labor (PTL). STUDY DESIGN: Two hundred and forty pregnant women at risk for PTL with intact membranes or preterm premature rupture of the membranes (PPROM) were randomly allocated to receive either two intramuscular injections of 12 mg betamethasone at 24-h intervals or 4 injections of 6 mg dexamethasone at 12-h intervals. Blood tests for WBC and differential count, ESR and fasting plasma glucose were drawn before betamethasone or dexamethasone injection and after injection every 24 h for two days. Pregnancy outcome was assessed as Apgar score, fetal plasma glucose and length of gestation. RESULT: In the preterm delivery group with intact membranes, no significant differences were found between the two groups in the maternal serum indicators of infection. The mean gestational age at delivery, 1- and 5-min Apgar score were higher in the dexamethasone group than in the betamethasone group. In the PPROM group, a significant rise in WBC count was occurred (12.4 cells/mm(3) vs. 10.5 cells/mm(3), P < 0.001), none of the other maternal serum indicators of infection and outcome variables showed significant differences between the dexamethasone and betamethasone groups. CONCLUSIONS: Dexamethasone compared to betamethasone significantly increased WBC count in women with PPROM, but in women at risk of PTL with intact membranes none of the maternal serum indicators of infection showed significant differences.
ABSTRACT
BACKGROUND/AIM: Although weight loss in patients with type 2 diabetes is very important, available data on the effects of long-term weight change on blood pressure (BP), lipids and glycemic control in these patients are limited. The aim of this study was to assess the long-term impact of weight change on BP, plasma lipids and glycemic control among patients with type 2 diabetes receiving routine care. METHODS: During the mean [standard deviation (SD)] follow-up period of 9.2 (3.4; range 2-15) years, 7,712 patients with type 2 diabetes were examined to determine changes in weight, BP, plasma lipids and glycemic control using a linear mixed-effects model for repeated measures. The mean (SD) age of participants was 51.3 (10.5) years with a mean (SD) duration of diabetes of 6.3 (6.3) years at initial registration. RESULTS: The change in fasting plasma glucose and glycosylated hemoglobin (HbA(1c)) from baseline to the last follow-up examination was significantly more favorable in those patients who gained weight during follow-up than in those who lost weight or whose weight remained stable. Systolic and diastolic BP and lipids also rose more significantly in the group with weight gain. CONCLUSIONS: Although this population of type 2 diabetes in Iran had negligible weight change over mean 9.2 years, this weight gain was associated with an increase in BP and plasma lipids, but also an improvement in glycemic control.

PURPOSE: The aim of this study was to evaluate the effect of additional magnesium sulfate (MgSO(4)) 100 mg to intrathecal (IT) isobaric 0.5% bupivacaine 3 ml on spinal anesthesia in patients undergoing lower extremity orthopedic surgery. METHODS: In a double-blind randomized clinical trial, 79 American Association of Anesthesiologists (ASA) I or II adult patients undergoing lower extremity orthopedic surgery were recruited. The patients were randomly allocated to receive 100 mg MgSO(4) 5% (0.2 ml) plus 15 mg of bupivacaine 0.5% (MgSO(4) group) or 15 mg bupivacaine 0.5% combined with 0.2 ml normal saline (control group) intrathecally. Response to treatment was assessed as onset and duration of sensory block, the highest level of sensory block, time to complete motor block recovery, duration of spinal anesthesia, and postoperative analgesic requirement. RESULTS: The onset of the sensory block was slower in the MgSO(4) group than in the control group (13.3 vs. 11.6 min, P = 0.04), and the duration of the sensory blockade was significantly longer in the MgSO(4) group than the control group (106.5 vs. 85.5 min, P = 0.001). Total analgesic requirements for 24 h following surgery were lower in the MgSO(4) group than in the control group (96.8 vs. 138.5 mg, P = 0.001). Mean duration of spinal anesthesia was not significantly different between two groups (178.0 vs. 167.4 min, P = 0.23). CONCLUSION: In patients undergoing lower extremity surgery with spinal anesthesia, the addition of 100 mg IT MgSO(4) to 15 mg bupivacaine without opioid supplement, prolonged the duration of the sensory block, decreased postoperative analgesic consumption, and significantly prolonged the onset of spinal anesthesia.
